Bulletin

The solar activity was at low levels over the past 24 hours. The sun was spotless and the X-ray flux was below B-level. The solar activity is expected to remain at low levels for the next 24 hours since no sunspots is visible on the disc.

No earth-directed coronal mass ejections (CMEs) have been identified in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.

The solar wind conditions have returned to a slow solar wind regime. The wind speed decreased from 405 km/s to 340 km/s since March 04 around 17:00 UTC, the total interplanetary magnetic field remained below 7 nT, and the southward component fluctuated between -6 nT and 4 nT. The solar wind environment is expected to remain in the slow wind regime.

The geomagnetic conditions were quiet with periods of unsettled condition observed by Kp (NOAA) and Dourbes station (Kp, K-Dourbes = 3). We expect the geomagnetic conditions to remain mostly quiet.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 07 Stationen.
